WP SAML Auth 2.3.1 update now available

March 9, 2026

Pantheon has released version 2.3.1 of the WP SAML Auth WordPress plugin. This update adds a new filter for multisite environments to give developers more control over how SAML-provisioned users are added to sites. No action is required — existing behavior is unchanged.

What's new

  • Multisite user provisioning control — A new wp_saml_auth_auto_add_to_blog filter allows developers to prevent auto-provisioned SAML users from being automatically added to the current site. When set to false, users are created as network-level users without a role on any specific site, giving full control over site membership. The filter defaults to true, preserving existing behavior. See #465 for details.
Developer note

If you use the new wp_saml_auth_auto_add_to_blog filter and return false, the user passed to the wp_saml_auth_new_user_authenticated action will have no role on the current site. Any hooks relying on $user->roles being non-empty should account for this.

Update to 2.3.1 from the WordPress dashboard under Plugins > Installed Plugins, or download it from the WordPress Plugin Repository.

For more details, see the plugin changelog.
